Following the iOS device tracking ‘scandal’ earlier this year, Apple has told developers that starting with iOS 5 the handsets will no longer collect the unique device identification numbers (UDID).

The UDID though was a vital element for networks and developers to track users’ activities like ads clicking or moving between applications.

It seems that WDA has found a way around: on Friday the company announced the AppTracker, capable of tracking anonymously and without UDID, mobile user.

On top of bringing this big relieve to developers, the AppTracker can establish how many app downloads were originated by clicking on a mobile ad, and can also track users as they travel back and forth between mobile website and app.

This is truly a remarkable new tool for app developers that can now monitor real-time downloading users, how effective the ad campaign is, where downloads are coming from and whether the download is generated from a web ad or in-app ad.
